When I visited the Big Island of Hawaii, I was lucky enough to be there when lava flow was pouring from a cliff side into the water, creating a lava waterfall effect. There was a local tour company offering boat tours to get near the lava entry. I took a tour one evening and it ended up being one of the most incredible experiences of my life. My sense came alive while smelling the sulfur, feeling the heat and seeing the lava in all its glory.
